Low Power Draw from 14400F

[IntelNick]

Hey everyone. I installed the 14400F today, up from a 13400F (not a big upgrade, I know) but when using stress CPU on CPU-Z the 14400F is at most pulling about 45-50W. I do have an undervolt of -100. Just strange as the 13400f pulled more wattage with the same undervolt (58-62W).

I have the PL1/PL2 and such as high as I can get it (Asrock B760M HDV.2) on my basic board. Now all things considered, it benches well and beats similar benchmarks according to CPU-Z (I'm above 2-300 points vs other 14400's). But it's just strange that it pulls so little power.

Is there reason to be concerned? Or should I continue to rock with it?

Since posting this, I learned this wasn't stable at -100mv, so I put it back to Auto and ran PassMark. Scores are mostly in line with other "benchmarks" with a CPU score of 25589

You might want to use Cinebench / Y-Cruncher to get an idea of power consumption under full load. It could very well be CPU-Z is not loading the CPU up nearly as much as it could be.

I'd also recommend HWInfo to measure your power consumption as well if you aren't using it already. Tom's hardware reports the 14400 using 90 - 130w during full utilization depending on the application.

what are the voltages that the CPUs are running at?
maybe you have a terrible binned 13th gen and a very nice 14th and they are already 50-60mv apart at stock.

Using the CPU-Z Stress, it is running at .94V which seems pretty low to me. I put load line calibration at level 5 to see if scores changed any with a little more voltage. The .94 is after adjusting calibration, it was previously pulling like .91-.92V

After running Cinebench R23, it peaked at about 72W (according to CoreTemp, neither core got above 50c) and .95ish Volts. I mean things seem to be fine and scores are no different when force feeding it a bit more voltage so maybe just a nicely binned 14400F...?

After some more tweaking I suppose everything is fine. Solid score on Passmark with a 96th percentile rating.

If all your scores look good, it's probably just a combination of the unvdervolt + good silicon quality.

Thanks for the input. So far it's rock solid, scores look good, I guess I got a good-er chip this time around.

I don't think so.
I had such an "anomaly" with an i5-7600K. This processor ran stably, with air cooling, at 5250MHz all cores (4000 MHz default).

Cool, I mean after benching with various software most of the day I feel like it's stable at the stock voltage of about .93-.95 depending on load. I can only get it to pull about 72W max using Cinebench which isn't a bad thing, but it makes me wish I could OC this chip cause I bet it'd yield a great OC.
